Application filed June 8, 1905- Serial No. 264,298.

To (ZZZ whom it may concern:

Be it known that I, EDWIN FAIRFAX NAULTY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful locked mailing apparatus, mail-chute, or mailtubc so constructed and assembled that all parts composing such apparatus are fastened and securely held in place under lock and key by concealeddevices, which devices are in turn securely held in place and fastened under lock and key by a new and useful locking device or devices, of which the following is a specification.

My invention relates to a new and improved form of mailing apparatus, mail-chute,or mailtube in that the apparatus may be securely aflixed to a wall or other upright construction in such a manner that the aflixing and supporting fastenings are concealed from View and may not be removed except by unlocking and taking off and apart the locking devices hereinafter described.

My invention relates to a new and improved form of construction of mailing apparatus, mail-chute, or mail-tube in that the separate parts of such apparatus are fitted and made and assembled together in such manner that they are held together and in place securely, thus forming such apparatus complete by a series of devices which, in conjunction with such assembled parts, constitute a new and useful locked mailing apparatus, mail-chute, or mail-tube for the purpose of carrying downward letters or mail from the upper and intermediate floors of buildings to a receptacle located on the lower floor.

The object of my invention and my improved form of construction and design of parts is to provide a mailing apparatus, mailchute, or mail-tube which may be locked to gether and held in place on a wall or other upright form of construction so that it cannot be taken down or taken apart or opened or interfered with or robbed by an unauthorized person, and yet which is so constructed that it may be readily taken down or taken apart by an authorized person provided with a proper key for the purpose of cleaning or clearing or repair or other proper purpose; and also the object of my invention and my improved form of construction and parts is to provide a safe and secure means under lock and key of mail ing or posting or inserting letters or mail in a mailing apparatus conveying downward such letters or mail from the upper and intermediate stories or floors of buildings to a receptacle located on the lower story or floor, from which they may be collected by authorized collectors. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a cross-section showing my invention of a locked mailing apparatus, mailchute, or mail-tube complete; and Fig. 2 is a detailed View in cross-section and elevation of certain of the various new and improved parts which when assembled form my invention of a new and useful locked mailing apparatus, mail-chute, or mail-tube. Figs. 3, 4L, 5, 6, and 7 are views of parts in detail.

On Fig. 2 of the annexed drawings the first part A consists of a back, of wood or metal or marble or glass or tile or any other suitable material, into the face of whichare cut, let into, drawn, or stamped two parallel and continuous grooves, channels, or recesses marked (Z (Z. Into the bottom of these grooves are fitted bolts or other means of fastening the back A to a wall or other form of upright construction. These bolts are marked a w a, and the shafts of the bolts are sunk through the material of the back and fastened to a wall or other form of upright construction, and their heads are sunk below the bottom of the grooves, so the said heads of the bolts may not interfere with the exact fitting and engagement of other parts adapted to be fitted in the grooves, channels, or recesses. At other stated distances are also fitted into the grooves a [Z the parts marked B and Z 6, which are fastened to the back A. by the parts marked Z 'Z 6.

Over the back A is fitted the metal facing O, which is made with grooves marked 0 c, which closely fit into the grooves of A marked a 0. Into the bottom of c c at stated distances are cut apertures of suflicient size to permit the passage through them of the parts Z) Z) of B. Into the grooves 0 c are fitted the parts marked 6Z2 (Z of the sides marked D. The sides marked D are made of metal, rolled, bent, drawn, or cast, so that they shall present the grooves, channels, recesses, or moldings marked CZ (Z and (Z (Z and (Z cZ, said grooves or channels being of any crossscctional form suited to the purpose.

Into the bottom of the parts (Z (Z at stated distances are cut apertures of sufficient size to permit the passage through them of the parts marked Z Z, and these apertures corre' spond with the before-described apertures in the part c 0.

Into the parts or grooves of D marked (Z (Z is fitted by slipping downward the glass front marked E. Into the glass front E may be cut or left at stated distances openings or apertures fitted with a special mailing-slot (the subject of another application for patent) for the insertion of letters or mail into the completed locked mailing apparatus.

The grooves, channels, recesses, or moldings of D marked (Z (Z areof sufficient depth and strength to hold securely in place the glass front E; but for greater security and also for the purpose of ornamentation the parts f f of the bonding part F are placed at stated distances in the half-round grooves (Z (Z of the sides D and are there held in place by the form of the grooves (Z (Z, or they may be fitted permanently into (Z (Z with solder, if desired. The particular form of part F is not essential, however, to the construction of my invention.

The assembly of the parts A, (Z (0 a, B, and C, with their new form of construction, application, and use, form the back of my invention, and the assembly of the parts D, E, and F, with their new form of construction, application, and use, form the front and sides of my invention.

For the purpose of strengthening the apparatus and of holding in place the completed sections and of locking them in place I have devised the part I. The part I is made of metal shaped by bending, drawing, or other process so that it forms a band in the form of a channel or a channeled band from the edge 3 3/ to the edge .2- z. The ends of the sections of my invention fit into the part I, and the sections of glass front E are prevented from slipping downward by the cross-piece w w, which is fastened as shown and which is less than the thickness of the glass front E. Into the back grooves of I are cut apertures corresponding to the apertures in the parts 0 0, through whiclnpass extra parts B and Z Z, and the part I is locked in place then by the part G and a special device I X L, which is later explained and illustrated.

The part J is made substantially the same as described with reference to part I except that it is made wider and that in it is cut or left an opening which of itself may be used as a mailing-slot or which may be used to contain or hold or be fitted with a special mailing-slot device, in which case two of the cross-pieces marked w ware applied to the part J, as described.

The apparatus being assembled, the metal device marked Gr, with the apertures g g, is slipped into place in the grooves (Z (Z of the sides D, the apertures g g engaging the parts Z Z and the device Gr wholly filling the grooves (Z (Z. The parts Z Z project through the apertures g g of G, so that when the look I X L is placed over them the parts Z Z are exactly engaged by the parts of the lock 1 X L marked a 4;, so that when the bolt j) of the lock I X L is shot intov place by a proper key the whole apparatus is not only lock-fastened to the wall or other form of upright construction, but is also securely fastened together and held in position, and the various parts are locked in place in such manner that all fastenings are concealed and are under lock and key.

The locking device I X L is made with an outer casing of seamless die-struck or cast metal, and into the inner top of this casing are fitted the various parts of the lock. The under part of the lock 1 X L is left open, so that it may be quickly placed over and its parts engage the staples Z Z and wholly cover them and by so doing wholly conceal the methods of locking and fastening.

I am aware that prior to my invention mailing apparatus and mail chutes have been made; but I claim to be the original inventor of a mailing apparatus, mail-chute, or mailtube made for the purpose of conveying downward mail or letters from the upper and intermediate floors of buildings to a receptacle on a lower floor, which is constructed of parts so made and fitted that the apparatus is held in place and securely fastened to or on a wall or other upright form of construction by concealed fastenings and which is so made and fitted that the parts of the apparatus are securely held together and locked in position by the application of my locking device and its combination with the several parts of my apparatus, so that my apparatus may not be taken down or apart by an unauthorized person, and yet may be readily taken down or apart by an authorized person holding a proper key.
